I have also fought him, and seen this effect. Although, it might be that he has bad connection to ECC. He does seem to have something, though, again, it could just be bad connection, but you never know.

 

I have fought him numerous times, and it seemed the same way. One time, while fighting, he logged, and when he got back on, he immediately started swinging. Also, he does seem to run faster than people, even when people are using swift. 2
Edit: Also, as sleeper said below me, he never would have any potion effects, and he could outrun someone in speed 2.

 

well he was fast and when i was fighting him no pot effects where on

 

beilive it or not i added him on skype, and yes he did admit to hacks, using nodus and using speed, although skype proof doesnt count i would just like to add that

 

Everyone that has posted here, refresh yourselves on the rules of the complaint section. Stop commenting in this section.

 

These screenshots taken directly from the evidence supplied in this complaint would prove that your claims of this user not having potion effects as false:

Spoiler

The only other assumption would be server lag. There's no proof that I see this user used any mods at all. Stop making complaints simply because you are accusing users of "hacking" just because you can't kill them in pvp.

Locked.
